I like this quite a bit! I might have changed the color (maybe chrome) of the center structure in order to add a little contrast (post processing in PS), or maybe I'd have changed the color of the surrounding area, as I like the gold tones for the center structure, but you get the idea. Beyond that, I'd either have centered the central mass for more symmetry, or set it more off-center for a little more interesting artistic balance. And maybe the rusty color could toned down a bit to look more like gold or brass. But this image looks very cool the way it is! Nice contrasts of textures and depth of field effect. Thanks for sharing!
